In other embodiments of the invention, the weight (6) in the pawn (1) may also be placed in any other suitable position, and any other suitable material may be used, without being limited to magnets.
Returning to fig. 3, as shown in fig. 3, a solution buoyancy module, a weight sensing chip circuit, and a photo-sensing assembly may be included in the chess grid or housing (2). In one embodiment of the invention, the solution buoyancy module may be formed from a liquid volume (11), and the liquid volume (11) may contain a solution (10) and a buoyancy plate (9) therein. In one embodiment of the present invention, by way of example and not limitation, the liquid containing chamber (11) may be secured to a panel of the housing (2), for example in fig. 3 the liquid containing chamber (11) may be secured to an upper surface (surface film) of the housing (2) and be waterproofed. Those skilled in the art will appreciate that the liquid chamber (11) may be secured to the housing (2) by any suitable means, and is not limited to the securing means shown in fig. 3.
In one embodiment of the invention, the solution (10) may be a black sodium chloride solution and a sodium chloride ratio of 25%, as will be appreciated by those skilled in the art, in other embodiments of the invention, the solution (10) may also be a solution having any other suitable color and chemical and component ratios thereof, and the invention is not limited to solutions having any particular color and chemical and component ratios thereof.
In one embodiment of the invention, the buoyancy plate (9) may be of a material having a density lower than the solution (10). By way of example and not limitation, the buoyancy plate (9) may be PE foam having a density lower than that of sodium chloride solution. It will be appreciated by those skilled in the art that a buoyancy plate of any other suitable material is used, as long as its density is smaller than the solution (10) such that when the pawn (1) is not placed on the housing (2), the buoyancy plate (9) may be suspended on the solution (10), and when the pawn (1) is placed on or moved to the housing (2), at least a part of the buoyancy plate (9) may be immersed in the solution (10) under the downward pressing action of the surface film on the upper surface of the housing, such that the level of the solution (10) rises.
In one embodiment of the invention, the liquid reservoir (11) may have a volume scale value for indicating the level or volume of the liquid (10) such that the volume scale value may change (create a difference) when the level of the solution (10) rises due to at least a portion of the buoyancy plate (9) being immersed in the solution.
In one embodiment of the invention, a weight-sensing chip circuit (4) is arranged below the liquid containing cavity (11), the weight-sensing chip circuit (4) contains a master chip thereon, and a photo-sensing assembly (8) is connected to the weight-sensing chip circuit (4). In this embodiment of the invention, as shown in fig. 4, the photo-sensing assembly (8) is arranged on the weight-sensing chip circuit (4) (on both ends) and on both sides of the liquid-containing chamber (11) for reading the volume scale value on the liquid-containing chamber (11). As will be appreciated by those skilled in the art, the arrangement of the liquid reservoir (11), the weight sensing die circuit (4), and the photo-sensing assembly (8) in fig. 4 is merely exemplary and not limiting, and any suitable arrangement may be employed in other embodiments of the invention to arrange the liquid reservoir (11), the weight sensing die circuit (4), and the photo-sensing assembly (8) so long as the photo-sensing assembly (8) is capable of reading the volume scale value on the liquid reservoir (11) and communicating with the weight sensing die circuit (4) to communicate information about the volume scale value.
In one embodiment of the invention, when the pawn (1) is placed on or moved to the housing (2), as described above, the pawn (1) presses down on the surface film of the housing (2) under the force of gravity and thereby presses down on the buoyancy plate (9) such that at least a part of the buoyancy plate (9) is immersed in the solution (10). At this time, the difference between the volume scale value on the liquid containing cavity (11) and the volume scale value when the chessmen (1) are not placed reflects the rise of the liquid level of the solution (10), and the volume scale value (the volume scale value before and after the chessmen are placed) is read by the photoelectric sensing component (8) and fed back to the weight sensing chip circuit (4) (specifically, fed back to the main control chip on the weight sensing chip circuit (4)). In this embodiment, the photo-sensing assembly (8) may be configured to read the volume scale values before and after the pawn is placed on the grid, respectively, to enable timely reading of information about the level change of the solution.
When the weight sensing chip circuit (4) receives the volume scale value, the main control chip on the circuit can calculate the weight of the chess piece (1) according to a buoyancy calculation formula, and the specific calculation process is as follows:
when the chess is not placed, the buoyancy plate (9) is in a suspension state in the liquid containing cavity (11), and the main control chip can read the volume data, namely the volume scale value, of the liquid containing cavity (11) at the moment.
When the chessmen (1) are put or moved to the chessmen grid (2), the downward extrusion of the chessmen (1) leads at least a part of the buoyancy plate (9) to be immersed in the solution (10) in the liquid containing cavity (11), the main control chip on the weight sensing chip circuit (4) obtains the volume scale value read by the photoelectric sensing component (8),comparing with and differencing the volume scale when not placing chess, the main control chip can calculate the volume data V of the solution (10) discharged by the buoyancy plate (9) Row of rows 。
From archimedes' principle it follows that: the object immersed in the liquid is subjected to an upward buoyancy force equal to the weight force of the object to displace the liquid, as shown in the following formula:
F floating device ＝ρ Liquid and its preparation method V Row of rows g，
Wherein density ρ of the solution Liquid and its preparation method Is known, ρ Liquid and its preparation method V Row of rows The mass of the discharged solution can be obtained. Therefore, the main control chip can be based on the volume data V of the solution (10) discharged by the buoyancy plate (9) Row of rows To calculate the buoyancy force F born by the buoyancy plate (9) and the chess (1) Floating device 。
Then, the Archimedes principle shows that the buoyancy born by the object is equal to the gravity of the object, and the buoyancy is shown as the following formula:
F floating device ＝G Row of rows ，
Namely, the buoyancy force born by the buoyancy plate (9) and the chess pieces (1) is equal to the gravity G of the buoyancy plate (9) and the chess pieces (1) Row of rows . And gravity G Row of rows Can be represented by the following formula:
G row of rows ＝m Row of rows g，
Therefore, the master control chip can calculate m Row of rows Data due to m Row of rows ＝m Buoyancy plate +m Chess pieces And the mass of the buoyancy plate is known, from which the pawn weight can be calculated. Because the weight of the chessmen corresponds to the identity of the chessmen one by one, the main control chip can determine the identity of the chessmen based on the weight and determine the real-time position of the chessmen according to the row and column positions of the chessmen in the chessman matrix of the chessboard.
As will be appreciated by those skilled in the art, the above-described calculation is merely exemplary and not limiting, and any other suitable means may be employed in other embodiments of the invention to calculate the weight of the pawn based on the volume data of the buoyancy plate displacement solution.
In one embodiment of the invention, the chess board (2) further comprises a metal spring piece (7) arranged at the bottom, and the metal spring piece (7) is used for enabling the weight sensing chip circuit (4) to be in contact with the FPC signal line (5) on the chessboard so as to be connected to a main board in the chessboard, so that the weight sensing chip circuit (4) can transmit the determined identity and position of the chess pieces to a CPU in the main board.
Figure 5 is a flow chart of a method for identifying the identity and location of pawns by weight according to one embodiment of the invention. In one embodiment of the invention, the method 500 of FIG. 5 may be performed by the weight sensing control module of FIG. 2, which includes a liquid containing solution and buoyancy plates, a photo-sensing assembly, and a weight sensing chip circuit, as shown in FIG. 3.
The method 500 begins at step 502. In step 502, the photo-sensing component reads the volume scale value of the solution in the liquid cavity and feeds it back to the weight sensing chip circuit. In one embodiment of the invention, the photoelectric sensing assembly reads the volume scale values before and after the chessmen are placed on the weight sensing control module and communicates them to the main control chip on the weight sensing chip circuit, respectively.
At step 504, when a pawn is placed on the weight sensing control module such that at least a portion of the buoyancy plate is immersed in a solution, the weight of the pawn is calculated by the weight sensing chip circuit based on the change in the volume scale value before and after placement of the pawn. In one embodiment of the present invention, step 504 further comprises: calculating the volume of the buoyancy plate discharged solution based on the difference between the volume scale value before and after the chessman is placed by the weight sensing chip circuit; determining, by the weight sensing chip circuit, buoyancy experienced by the pawn and the buoyancy plate based on the calculated volume; and calculating, by the weight sensing chip circuit, the weight of the pawn based on the buoyancy. As mentioned above, since the density of the solution is known, the volume of the displaced solution can be used to calculate the weight of the displaced solution, i.e. the buoyancy experienced by the buoyancy plates and pawns. The buoyancy force is now equal to the weight force of the buoyancy plate and the pawn, and since the mass of the buoyancy plate is known, the mass of the pawn can be deduced.
In step 506, the identity and location of the pawn is determined by the weight sensing chip circuit based on the weight. In an embodiment of the invention the pawns are provided with weights such that each pawn has a different weight and the weight of each pawn corresponds to its identity. In one embodiment of the invention, the weight-sensitive control module comprises a housing that is used as a grid for placing the pawns, the grids being arranged in a matrix in the board, and the positions of the pawns being indicated by the row and column values of the grid in the board matrix.
After step 506, the method 500 ends.
Embodiments of the present invention have been described above with reference to block diagrams and/or operational illustrations of methods, systems, and computer program products according to embodiments of the invention. The present invention is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present invention are intended to be included in the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
